Core Advantages: Why the BR2335 Leads the Industry
1. Peak Energy Density (280mAh Capacity)
The 3.5mm thickness allows us to maximize the active chemical materials inside the cell, pushing the capacity to a robust 280mAh. This ensures significantly longer device autonomy compared to standard 3V coin cells, drastically reducing the total cost of ownership (TCO) for end-users by eliminating frequent battery replacements.
2. Flawless Extreme Temperature Operation (-40°C to +85°C)
Industrial hardware operates in the real world, not just climate-controlled labs. The advanced Li-CFx chemistry guarantees a stable, fade-free voltage output whether the battery is exposed to the freezing -40°C nights of an outdoor security grid or the +85°C ambient heat of a densely packed enterprise server room.
3. Decade-Long Standby Reliability (<2% Annual Self-Discharge)
Engineered for longevity, the BR2335 features a remarkably low self-discharge rate of under 2% per year. Devices can sit in inventory or standby mode for up to 10 years, and the battery will still deliver reliable Real-Time Clock (RTC) and SRAM backup power the moment it is needed.
Target Applications: Powering Mission-Critical Infrastructure
The sheer 280mAh capacity of the BR2335 makes it the premier choice for heavy-duty commercial and industrial electronics:
Enterprise Servers & Data Centers: Acts as the ultimate high-capacity CMOS/RTC backup, ensuring complex system clocks and RAID configurations are safely preserved during prolonged power grid failures.
Point of Sale (POS) & Smart Retail: Protects sensitive offline financial logs, mobile payment gateway encryption keys, and continuous transaction records.
Commercial Security & Access Control: Delivers relentless, years-long power for electronic smart locks, high-drain remote security sensors, and perimeter alarm panels.
Industrial IoT & Smart Metering: The preferred power source for utility meters and remote telemetry devices that require a 10+ year uninterrupted field life.
Engineering Insight: Li-CFx vs. Standard Chemistry
Why choose the BR2335 over standard Lithium Manganese Dioxide (CR) batteries?
The answer lies in the flat discharge curve and chemical stability. While standard CR cells suffer from a continuous, sloping voltage drop as they deplete, Omnergy’s BR-series utilizes a Lithium Carbon Monofluoride (Li-CFx) system. This provides a perfectly flat, consistent 3.0V output until the very end of its lifecycle, entirely preventing low-voltage brownouts in sensitive microprocessors. Furthermore, CR batteries can swell or leak at temperatures above 60°C, whereas the BR2335 remains completely stable and safe up to a blistering 85°C.
